86 Ford Ranger super cab, 2.9 liter 5 speed manual trans.

This may sound dumb, But can anyone tell me what way is the right way for the center support bearing to go on. The center support bearing I have has a rubber lip sticking out on one side about a half an inch give or take a bit. Does that side face the trans or does it face the rear end?

Thank you for your time and help...
